SPECIFICATION forming part Of Iiitters Patent N 0. 730,178, dated June2, 1903.

Application filed January 24,1903; Serial No. 140,354. (No model.)

e it known that I, MATHIS HARDEE VAUGHAN, a citizen of the UnitedStates, re-

siding at Huntsville, in the county of Madison and State of Alabama,have invented a new and nsefulgGage for Setting Rollers of Roving andSpinning Machines and the Like, of which the following is aspecification.

This invention relates to a gage for setting rollers of roving andspinning machines-and the like; and-it has for itsjobject to providesuch a gage which is especially adapted for setting the top rollers ofsuch machines per fectly straight and parallel with'jthe bottom steelfluted rollers,the top rollersusuallybein g leather-covered and thelength of lifeaof this covering and the efficiency of the machinesdepending largely on the exact ad justiuent of the rollers. v Generallyspeaking, the top rollers of roving and spinning machines rotate instands f'heads 9, and screw-threaded ends 10. The 'scr'eW-threadedends10.0f the lugs 6 are of a which rest on the bottom rollers and which areadjustable on spindles projecting from the cap-bars of the machines.Heretofore the top-roller stands have been set by interposing blocks ofsupposedly-uniform thickness between them while they were being adjustedand locked in the desired positions. How ever, this means of adjustmenthas been-found unsatisfactory, for the reason that it is notalwaysconvenient to get blocks of exactly the same width and because thestands themselves vary in thickness and other details of construction,the results being that the top rollers were not brought in everyinstance into exact parallelism with the bottom rollers.

This invention is designed to overcome the defects prevalent in thecommon method of adjustment and to provide a simple and eflicient meansto properly set in every instance the top rollers with relation tothebottom rollers, no matter What variations there might be in the toproller stands.

One adaptation of this invention is shown for purposes of illustrationin the accompanying drawings, in which like reference characters referto corresponding parts in the several views, and in which- Figure 1 is aperspective view of the gage. Fig. 2 is atop view, one of thesetting-lugs being removed to show details. Fig. 3 is a side view. Fig.4 is an enlarged view of anengaging or setting lug, and Fig. 5 is anenlargedsectional view of another form of the engaging or settinglug.

w Referring more particularly to the drawvided iigits centrallongitudinal line with 1011:

gitudinaltslots 5. p

- Each lug 6 comprises in its construction a substania'llytrnncated-cone-shaped portion 7 and a bolt 8, passing through saidportions 7 at right angle to its parallel planes. Each bolt 8 has a head9 projecting from a plane of portion 7 and a screw-threaded end 10projecting from the other plane of said portion and provided with anengaging nut'll. If desired, lugs 6'1can be turnediu one piece, havingenlargedcentral portion 7, projecting diameter to correspond with thewidth of the through the slotsgand thelugs being adj ustably heldby thenuts 11, these nuts bearing against one side of the plate 1 and a planeof the enlarged central portions 7 bearing against the other side.

, The mode of use of this invention is substantially as follows: Thetop-roller stands on one spindle'are set as desired, the top rollershaving beenlifted out. Thegageisthenplaced with one of its edges 2resting on the bottom rollers, these edges being cut away, if desired,as at 12, so that the gage rests only on the outside rollers. One of theedges 4 of the T.-squ'are engages the outer bottom roller. As many lugs6 are provided as there are roller-stands on a single spindle. I Theheads 9 of the lugs are made exactly the same diameter as the journalsof the top rollers and the width of the slots of the stands in whichthese journals rotate, and these heads are designed to engage thesesubstantially vertical slots of the stands when the gage is in use. Thewidth of the gage between the edges2 is exactly the same as the diameterof the top rollers, and for this reason and because the gage when in useand the top rollers when placed in their stands both rest on the bottomrollers the heads 9 are adapted to engage the slots of the stands atexactly the point where the journals of the top rollers rotate. When thegage is in position as described and the heads 9 are in engagement witha corresponding number of roller-stands, the lugs 6 are set by the nuts11. The gage is then ready to set other top-roller stands in exactlysimilar positions as the first group of stands, the gage being placedacross the bottom rollers as when it itself was to be set, as describedabove, and the heads 9 engaging the top-roller stands. The stands arethen set and locked on their spindle while held in correct position bythe lug-heads 9. The gage being similar on each edge and the lugs havingthe same relation to one edge as to the other, either side of the gagemay be used for setting the stands from either the right or left side,as the case may be. In this manner the top-roller stands on everyspindle throughout a certain group'of machines or throughout an entiremillare set in exactly similar positions with relation to the bottomrollers, which results in the top rollers being exactly parallel withrespect to the bottom rollers. This insures uniformity of product andprevents undue wear on the top-roller coverings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A gage of the character described, comprising a main portionconstituting a T- square, and a lug projecting from said main portionand adjustably movable thereon, said lug having means thereon forlooking it to said main portion, a portion for engaging apertures in thearticles to be set, and an enlarged portion for abutting said articles,substantially as and for the purposes described.

2. A gage of the character described, comprising a flat plate,longitudinally-disposed slots in said plate, and engaging lugsprojecting from said plate and adjustable in said slots, said lugshaving a portion for engaging apertures in the articles to be set, andan en larged portion adjacent said engaging portion for abutting saidarticles, substantially as and for the purposes described.

3. A gage of the character described, comprising a main portionconstituting a T- slots, said lugs comprising a slot-engaging portion,an enlarged central portion, and a smaller portion for engagingapertures in the articles to be set, substantially as and for thepurposes described.

5. A gage of the character described, comprising a flat plateconstituting a T-square, cut-away portions in the longer parallel edgesof said plate, longitudinally-disposed slots in said plate and arrangedequidistant from each other and midway between the longer parallel edgesof said plate, and engaging lugs projecting from said plate andlongitudinally adjustable in said slots, said lugs comprising aslot-engaging portion of diameter corresponding to the width of saidslots and having thereon means for locking said lugs to said plate, anenlarged portion adjacent said plate, and a smaller portion for engagingapertures in the articles to be set and of a diameter corresponding tothe width of said apertures, substantially as and for the purposesdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. v
